銅中含氧(煉銅時(shí)容易混入少量氧)對(duì)導(dǎo)電率影響很大,用于電氣工業(yè)的銅一般都必須是無(wú)氧銅。另外,鉛、銻、鉍等雜質(zhì)會(huì)使銅的結(jié)晶不能結(jié)合在一起,造成熱脆,也會(huì)影響純銅的加工。這種純度很高的純銅,一般用電解法精制:把不純銅(即粗銅)作陽(yáng)極,純銅作陰極,以硫酸銅溶液為電解液。當(dāng)電流通過(guò)后,陽(yáng)極上不純的銅逐漸熔解,純銅便逐漸沉淀在陰極上。這樣精制而得的銅;純度可達(dá)99.99%。 </p> <p> <br /> </p> <p> 紫銅富有延展性。象一滴水那么大小的純銅,可拉成長(zhǎng)達(dá)兩公里的細(xì)絲,或壓延成比床還大的幾乎透明的箔。紫銅**可貴的性質(zhì)是導(dǎo)電性能非常好,在所有的金屬中僅次于銀。但銅比銀便宜得多,因此成了電氣工業(yè)的“主角”。 </p> <p> <br /> </p> <p> <br /> </p><div

銅排表面鍍錫，作用一是防止銅排氧化、二是改善銅排連接接觸面，又因?yàn)?，金屬錫與銅結(jié)合層面會(huì)形成一種合金，增強(qiáng)了銅排鍍層附著力，此外金屬錫導(dǎo)電率還不錯(cuò)。致密性好、光潔度高、增強(qiáng)了被鍍件耐磨性。 </p> <p> <br /> </p> <p> 銅排涂漆：此工藝屬于淘汰落后工藝，現(xiàn)很少使用。工藝：三相交流電路母線均涂黑漆，顯眼處粘貼色標(biāo)，A相為黃色，B相為綠色，C相為紅色，零線或中性線涂淡藍(lán)色漆，安全用接地線涂交替黃綠雙色漆，無(wú)法區(qū)分極性、相序者涂白漆。 </p></p><br /><p>文章來(lái)源地址:
